Okay, so this is my list, depending on the circumstances the Exalted on foot will either join with the Chosen, or with the Marauders in a 10x3 rank. The BSB will join with the Knights, and the rest will journey up the middle, I will make a fort for my Sorcerer with my core warriors with both Warriors going on the left and right while the Chosen in front, hopefully with the right spells and dice rolling I may be able to get the No.6 spell in Nurgle.

The War Shrine will probably tend to stick around the center giving the War Shrine powers out.

To be honest it looks good. You've got a bit of everything and the character choices are well balanced.

The only real things I might change are:

1: The Marauder Exalted, he doesn't need the shield if he's got a 3+ Ward. Give him a Halberd or something to help with the blood letting.

2: Persoanlly I'd put the Blasted Standard on the Chosen. It's your biggest block of troops so therefore will get the majority of the attention. The knights, with their 1+ Save, are usually alright from missile fire. Well, except Cannons and Bolt throwers.

3: If you gave the Blasted Standard to the Chosen you could then give the Knights the Banner of Rage. This leaves your BSB able to take the collar of Khorne or a similar Magic item that will give the knights some Magic Resistance. If anyone has the Lore of Metal those Knights are going to be option number 1

1: The Marauder Exalted, he doesn't need the shield if he's got a 3+ Ward. Give him a Halberd or something to help with the blood letting.

That's exactly what I was thinking when I read this list.

Blasted standard on the chosen could work. I don't like +1 movement for only 1 block of troops, it breaks up your battle line too much, exposes flanks and such too easily. They're much better served with the rapturous standard, or maybe the +1 leadership. Either or, I think its better than +1 movement.

I like the blasted/rage combo on your knights, but your BSB is way too vulnerable as is. Magic banners on WoC BSBs usually is a bad idea. However, if you want to keep it this way, I suggest swapping the banners between the knights and BSB. Your BSB has a good chance of dying when you finally make it to combat, so what this does is it keeps your knights raged even if he does die. And if he does die in combat you lose the shooting ward save, but you're already in combat so it doesn't matter.

Your Nurgle sorcerer benefits nothing from the golden eye of tzeentch. I doubt he'll be left alone for a lucky shot to take him out so easily, you'd be far better off giving him something like the collar of khorne. Gives your block of troops MR2 as well as some type of defense for him in the 6+ ward.

So all that comes up to 2392 points, made most of the changes mentioned, I also added the Conjoined Homunculus onto the Sorcerer just because I had the points for it, plus it ain't bad being able to add D3 to your total casting value!
